Project Example – Using Helical Capacity Design Software for Helical Pile Foundation Bid

Posted by Gary L. Seider, PE on Nov 4, 2021 10:09:00 AM

We’re often asked by engineers and contractors how to bid helical pile foundations. This often happens when the geotechnical report for the project does not provide specific recommendations for the helical piles, i.e., pile type and length, helix configuration, and capacity. One of the best tools available to design helical piles based off a geotechnical report is HeliCAP® v3.0 Helical Capacity Design Software. The soil boring information can be taken directly from the geotechnical report and input into HeliCAP. Within minutes, the software will provide everything necessary to competitively bid the project.

3 Advantages of Helical Tiebacks vs Conventional Grouted Tendon Methods

Posted by Fernanda Osborne on Nov 1, 2021 10:02:00 AM

CHANCE® helical tiebacks are a pre-engineered mechanical anchoring system for permanent and temporary shoring. The success of the helical anchor tieback system is based on decades of similar use of CHANCE anchors in the electric utility industry. Capacities up to 200,000 pounds per anchor are obtainable with this “instant” tieback shoring method. CHANCE tiebacks offer a fast, cost-effective and simple solution for any tieback project.

Deep Foundation “Feedback”: Valuable Early Data From The Jobsite

Posted by Nate Seguin, PE on Oct 5, 2021 8:15:00 AM

The Reality
A recognized challenge for geotechnical engineers designing deep foundations is utilizing information on subsurface soils from a finite number of subsurface explorations (e.g., test borings with Standard Penetration Test sampling).  If the geotechnical engineering consultant that was hired to coordinate and report on the explorations performs their work within the standard of care, the number of explorations performed at the site is appropriate and useful for characterization of a site’s soil profile.  From a well-coordinated subsurface exploration program, a geotechnical engineer is able to develop a representative understanding of the composition and strength of subsurface soils (including rock and obstructions where present) at a site.  It’s no mystery that SPT boring logs per ASTM D-1586 are routinely used in the design of deep foundations, especially considering the many empirical correlations between SPT blow count and engineering properties of soils that have been established since the test method was standardized in the mid-1950s.

…there’s more! Foundations of Capital “S” Sustainability

Posted by Brent Adams on Sep 22, 2021 6:45:00 AM

A bit more obtuse than my last article, but definitely something to think about are the broader impacts that helical piles can influence when expanding the focus from product-specific sustainable features to a broader capital-S Sustainable community perspective…

“Foundations” of Sustainability

Posted by Brent Adams on Sep 14, 2021 2:50:42 PM

For buildings and structures, material selection, energy conservation methods and good water efficiency are important parts to consider when thinking of sustainability. However, thoughts about what could be considered a sustainable foundation are often overlooked (or don’t go much “deeper” than costs or what LEED points it can qualify for). Let's explore how CHANCE helical piles effect the environment, economy, and society to create a more holistic view of what it means to be sustainable.

Helical Anchors: The Superior Choice for Mooring Applications

Posted by Stephen Scott, EIT on Sep 7, 2021 10:39:00 AM

On land, piling and anchoring solution are abundant and helical anchors have always been known to be cost-effective, versatile, and easy to install. Offshore, however; helical anchors stand alone as the superior choice for mooring applications. First used in the marine environment to secure oil pipelines to the ocean floor, helical anchor technology has been proven to be a successful and environmentally sensitive alternative to traditional mushroom, deadweight, and pile anchors for boat owners, harbormasters, and marine construction and civil engineering firms.

High Capacity Helical Pile Construction at Dry Tortugas National Park

Posted by Foundation Technologies, Inc. on Aug 31, 2021 2:00:00 PM

Dry Tortugas National Park is home to historic Fort Jefferson which was constructed for the protection of valuable shipping lanes in the Gulf of Mexico and along the eastern seaboard. The small remote island, only accessible by boat or seaplane, is located 70 miles west of Key West in the Gulf of Mexico and is surrounded by waters, beautiful coral reefs, and protected marine life.

Objecting to Obstructions in Deep Foundation Installation

Posted by EBS Geostructural on Jul 15, 2021 8:45:00 AM

Obstructions can be difficult, because you often do not know they are there until you begin to install a deep foundation. Helical piles cannot install through obstructions; however, here we highlight the different options you have for dealing with obstructions while installing helical piles. One of the benefits of helical piles is that you do not have to abandon the pile. In most cases, it can be removed and reinstalled (unlike other deep foundation options).
